The set to store different groups of triples in the form of {sub1: {pre1: {obj1}, pre2, {obj2, obj2_1}}, sub2: {pre3: {obj3, obj3_1}, ...}, ...}

Implementation

// TODO: turtle subject as a BlankNode as subjects can be {iri, BlankNode, collection}, and iri can be {IRIREF, PrefixedName}, the current implementation only deals with iri (implemented as URIRef) as subject.
